Title: Bag and tube folding method and apparatus
Inventor: JOHNSON WILLIAM C
IPC: B31B39/26
Filed: 1988-08-26
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE This invention is directed to a method for folding a tube into radially superimposed accordion pleats in which the tube is first placed in tubular form and clamped against radial and longitudinal movement at circumfer-entially spaced zones adjacent an open end of the tube.  A first annular band of the tube is then forced radially outwardly and longitudinally to a position radially out-wardly of the clamped zones, and is connected by a bight to the remainder of the tube, a part of which forms a second annular band lying radially outwardly from the first band. The two annular bands and the part of the tube containing the  spaced  zones are then clamped against radial and longitudinal movement, and a series of additional pairs of bands are then sequentially formed radially outwardly from the second band in the same way that said first and second bands are formed, with periodic clamping of all of said bands against radial and longitudinal movement occurring after each additional pair of bands is formed.   This invention also covers an apparatus for placing radially superimposed accordion pleats in a tube which includes a forming structure to hold the tube in a distended tubular form while it is alternately contacted by a series of clamping fingers and a series of pleat folding fingers, which latter fingers function to move sections of the bag radially outwardly and longitudinally into a configuration constituting radially superimposed bands.

Title: Data compaction method for microprocessor cards
Inventor: LICHTY RONALD D
IPC: H03M7/46
Filed: 1988-10-05
Granted: 1991-12-31
Abstract: ABSTRACT OF THE DISCLOSURE       A data compaction method, for writing data in highly compact binary form in a data storage medium using a microprocessor, compresses serially occurring transaction values in a limited memory space by substituting prefix codes for previously occurring values and for commonly occurring previous values.  The previous values are listed and updated on tables by the microprocessor so that they are indexed to the prefix codes adaptively to changing local values and changing common values over time   The data compaction method is particularly suitable for an account card having a limited, non-erasable memory used in an automated transaction terminal for maintaining an account record of transactions in frequently recurring amounts.  A postage metering terminal is operated by the account card, in which an initial balance has been written and each purchase of postage is recorded.  A current balance is recomputed by parsing the previously recorded data   If the current balance is sufficient, the requested value is recorded in compressed form in the card memory, and the terminal is operated to print or dispense the requested postage.
